(Cl. 215-47) This invention relates to internal capsule closures for sealing bottles, jars and other receptacles. Its object is to provide a closure which is inexpensive to manufacture, easy to apply,

hygienic in use, may be readily opened and affords safety against surreptitious refilling. 7

According to the invention a capsule of foil or other suitable material is provided with an internal stiffener which enables it to be introduced 19 with its open. end downwards into the neck of the bottle or other receptacle so that the side of the capsule is clamped between the stifiener and the inner wall of the neck of the bottle or other receptacle. 1

The capsule is introduced into the neck of the bottle or other receptacle like an ordinary cork and, as previously mentioned, with its open end downwards. As the capsule ispressed into the neck of the receptacle, the stiffener takes up the pressure of the stamper or whatever other stoppering device is employed and ensures tight contact between the cylindrical side-wall of the capsule and the irmer wall of the neck so that the air is compressed within and below the cap- 5 sule and its tendency to spread out the cylin drical wall of the capsule causes the,latter to adhere closely to the neck. A tight closure is thus obtained and moreover, the thin capsule, when once introduced, cannot be removed without being damaged so that a closure made in accordance with the invention will aiford also safety against surreptitious refilling. To protect the capsule against accidental damage, it 'may be sunk below the plane of the orifice of the receptacle.

In order that the invention maybe clearly understood and readily carried into eflect, the same will now be described with reference to the accompanying drawing, in whichz- Figure 1 is sectional elevation of a bottle a flanged stiffening ring;

bottle neck which receives the capsule tapers internally to some extent in order to ensure tight contact between the cylindrical side of the capsule and the inner wall of the bottle neck owing to the jamming of the cylindrical stiffener b in the neck due to the tapered form of the latter.

Figure 2 shows a modified form of stiffener b consisting of aplain cylindrical ring.

In the form of the invention shown in Figures 3 and 4, the stiffener b has a contracted portion c at its upper end, forming a well-rounded discharge orifice which prevents, when the bottle is emptied, the jet of liquor from coming into contact with the edge of the bottle mouth.

It has been found that by using capsules made of aluminium foil about 0,002 in. thick in conjunction with, stifieners made of aluminium in the shapes shown in Figures 1 and 3 and with walls about 0,008 in. thick, permanently air-tight closure of a bottle mouth of an inner diameter of 1 inch may be obtained.

What I claim isf- 1. A closure for bottles, jars and other receptacles, which consists of a thin-walled capsule open at one end and provided in its interior with an annular stiffener, the whole being introduced with the open end downwards into the neck of the receptacle so as to cause an annular side portion of the capsule to be clamped between the stiffener and the inner wall of the neck of the receptacle.

2. A closure for bottles, jars and other receptacles as' claimed in claim 1, wherein the annular stiffener has a contracted portion at its upper end, said contracted portion forming, when the top of the capsule is removed, a well-rounded discharge orifice.

Figures 3 and 4 are sectional elevations of another form or the invention showing the capsule intact and broken, respectively.

Referring first to Figure 1, a designates a capsule of foil with a. cylindrical wall fitting into a 50 bottle neck and lined with an annular stiifener b of L-shaped cross-section. The outer diameter of the stifiener b equals the inner diameter of the cylindrical portion of the capsule a. The height 01' the stifig'ner b may be less than that 55 of the capsule a.
